Alzheimer's runs in my family so I am well-versed on what a person with Alzheimer's does, how he behaves, and what he looks like. The presentation of this person with Alzheimer's is way out of line with anything I have ever seen. I stopped watching the movie after he was diagnosed with the disease because I got so turned off with what I was seeing. The writer(s) clearly never met a person who had Alzheimer's.
